The Trollbeads Black Silk bead is very different from the typical glass bead. Mine is black with a hint of greyish-green. 

   
 
It goes really well with a black and white theme. 

  
I wanted to add a pop of red, so used my Ohm Beads Nuts & Berries bead on the Twisted Bangle. 

  

Stopper and all silver beads are by Redbalifrog.  

Beads 4/6/8/10 are by Trollbeads. 

The middle white faceted bead is by Pandora.
